On Ubuntu 16.04 LTS seems not working

[haizen007]

I made a fresh install from 1.2.0 -> 1.3.0 and from Ubuntu 14.04 -> 16.04.
On the old server everything was fine.
Now, on the new Ubuntu, both LG versions doesn't works and I don't know why.
when I click on "Run Test" nothing happens.
Yes, I followed the config.sh -> "Installation is complete"
Running on apache 2.4.

I am having the same issue on Debian 8 64bit, I have compared it with a known working install on CentOS 7 everything matches up.

[havok2]

I had the same problem. Changed directories to the LookingGlass subdir and ran the configure.sh script again, and everything worked again.

[haizen007]

Move assets to the LookingGlass sub dir? I think I did not understand...

[Backtogeek]

I see, I have no idea why it is required by I copied the 'assets' directory in to the LookingGlass directory, reran the config and it works fine now.

Edit: scrap that, its a problem with the LookingGlass/ratelimit.db

If you change rate limit to 0 in Config.php everything works again (obviously that disables rate limiting)

[haizen007]

it is not working for me. http://lg.yonathan.com.br

[Backtogeek]

did you set $rateLimit = (int) '0'; in Congif.php

?

[haizen007]

Yes

// IPv4 address
$ipv4 = '104.238.129.33';
// IPv6 address (can be blank)
$ipv6 = '2001:19f0:300:4165::64';
// Rate limit
$rateLimit = (int) '0';
// Site name (header)
$siteName = 'LookingGlass';
// Site URL
$siteUrl = 'http://lg.yonathan.com.br';
// Server location
$serverLocation = 'New Jersey, NY - USA';
// Test files
$testFiles = array();
$testFiles[] = '10MB';
$testFiles[] = '100MB';
$testFiles[] = '1000MB';
// Theme
$theme = 'cerulean';

Sorry for the delay, I haven't tested LG on Ubuntu 16.04 yet, but my guess is it's a permission based issue.

I'll leave a quote from a previous issue: #32 (comment)

The problem is permission (SUID) based. The short of it is ping and MTR need root permission to open a socket, but some OS' have tighter privileges which prevent your web user (www-user) from accessing the commands.

Try these commands:

sudo chmod u+s `which ping`
sudo chmod u+s `which ping6`
sudo chmod u+s `which mtr`

You can try the above for the commands that do not work. If the issue still persists I'll have a look on 16.04.

[haizen007]

I tried and still not working.

Not sure if I'm doing something wrong, but seems pretty simple.
I've been using LG for a long time without any problem on 14.04 LTS, but now I'm completely lost to figure out.

I'm seeing the same thing on ubuntu 16

[dalenoe]

This is the culprit, haven't found a fix yet though.

PHP Fatal error: Uncaught Error: Function name must be a string in /var/www/html/LookingGlass/ajax.php:44

Missing php module? php not able to execute shell commands? I have looked at the permissions on /bin/ping and such and those look fine.

[dalenoe]

I'm starting to point the finger at PHP versions. Ubuntu 16 is using php7.x whereas all the errors I am seeing mention php5.6

[dalenoe]

A quick fix, is uninstalling php7, and installing 5.6.

It's definetely the PHP versions.

[dalenoe]

@haizen007 Try my fix above in the last comment. =)

[haizen007]

@dalenoe I thought it was that, but I prefer php7 instead of the old 5.6.
I can install the old one and change this virtual server to run on 5.6.
Anyway, I suppose that the LG should be improved to be able to run with new releases of PHP.

My current php -v:
PHP 7.0.13-0ubuntu0.16.04.1 (cli) ( NTS )

[Backtogeek]

I obviously had a different issue related to the ratelimit.db

I cant believe we got to this stage and the OP just now thinks it is relevant to mention it is php7, haha.

For PHP 7 compatibility you might want to try the changes in the fork by MartinVerges:

https://github.com/MartinVerges/LookingGlass/commit/175f48a9c32b2ec6f3aa7a2f84aee0b91399dd5b

Additionaly, if you are using sqlite as well, make sure to install the necessary dependencies for using sqlite on PHP 7.0.

[dalenoe]

Awesome. I will take a look at that this weekend.

Hi,

I have met the same problem in Ubuntu 16.04 LTS. And I have fixed it. Here I illustrate some steps, maybe it can be helpful.

1. Open PHP error log.
   vim /etc/php.ini
   Find display_errors, and changed to On. Then restart the webserver.

2. Run the code. Get the error information.
   For example, in my case, the error is proc_open() has been disabled for security reason.

3. Fix the problem.
   Edit the php.ini again, and find disable_functions = exec,system,dl,passthru,chown,shell_exec,popen,proc_open, remove proc_open here. Restart the webserver.
